    MP3350B SC547 ERROR

    We swapped out the fuser. SC547 came back. We swapped out the power supply (the one located on the left side under the exit tray) and was good for about 2 weeks, now SC547 came back....? I'm going to test the wall voltages and check for proper source.

    Any other suggestions?

    Thanks!

    If it was un-resettable until you replaced the PSU, then I suggest that there is some voltage issues taking it out.
    No surge suppressor?
    Next option is BICU
